Plumbing Schematic Diagram
An electric water heater can be fitted in
your home regardless of the type of plumb
ing system as in most cases they can
operate directly off the mains cold water
supply.
Fig.shows a typical system layout. Do not
use jointing compounds on any pipe fittings
for the installation.
The Unit works at minimum water flow rate
of 1.5 litre/min.
HANGING OF THE SHOWER
WARNING:The shower must not be
positioned where it will be subjected to
freezing conditions.
FOR EASE OF SERVICING,THE UNIT
MUST ALWAYS BE MOUNTED ON THE
SURFACE OF TILED WALLS. NEVER
TILE UP TO THE UNIT.
This product is splash-proof rated and is
approved for use in shower cubicles and
over baths.
However, do not install the unit in a position
where the sprayhead will consistently
direct water over it.
The shower unit MUST be positioned
vertically.

FILTER MAINTENANCE
It is recommended that the filter is
periodically cleaned in order to maintain
the performance of the shower.
'Open' the filter head from the stop valve.
Remove the Filter Net and clean it using
soft brush and wash it under running
water. Ensure all dirt particles are
removed.
'Close' it back after washing the filter.
TESTING RCD (For RCD Model Only)
Test the RCD Regularly
Turn On the unit with electric power and
water supply.The RCD-LED(Green)
should light up.

CAUTION:DO Not Test Stop Valve under dry condition
To adjust the shower temperature
The shower temperature is altered by increasing or decreasing the Power Control via the Control knob.
To increase the shower temperature Turn the control Knob clockwise towards the HI sign; this will increase the water temperature.
To decrease the shower temperature Turn the control Knob counterclockwise towards the LO sign; this will decrease the water temperature.
CAUTION:Be certain the showering temperature is satisfactory by testing with your hand before stepping under the sprayhead.lt is recommended that persons who may have difficultly understanding or operating the shower controls should not be left unattended while showering.

FIXING THE SHOWER TO THE WALL
Instructions for fixed appliances stating how
the appliance is to be fixed.
lmportant:The shower must be mounted on a
flat surface which covers the full width and
length of the backplate. It is important that the
wall surface is flat otherwise difficulty may be
encountered when fitting the cover.
1.1 Decide on a suitable position to allow for
cover fit and removal.
Determine the direction that you require the
inlet water supply and electrical cable to enter
the unit from.
Determine the height at which you require the
unit to be installed.
1.2 Remove the cover.
Mark the position of the unit on the wall. Mark
the positions of the fixing holes. Make sure
that sufficient electrical Supply cable is avail
able for connection to the terminal block.
1.3 Drill and plug the fixing holes. Secure the
unit to the wall with the screws provided. Avoid
drilling into any supply cable/pipe.
Note : Hook the backplate over the top screws
and fit the lower fixing screw into position. DO
NOT fully tighten the screws at this stage, as
the fixing holes are elongated to allow for out
of square adjustment after the plumbing
connections have been completed.

PLUMBING CONNECTIONS
COMPLETE THIS PROCESS BEFORE WIRING CON-NECTION
CONNECTION PROCEDURE: Connect the water supply to the inlet of the shower via 15mm c o p p er , s t a i n l e s s s t e e l o r p l a s t i c p i p e us ing a 15mm x 15mm elbow compression fitting. Do not use excessive force when making these connections.
FITTING THE STOP VALVE
The supplied stop valve or one with a fi lter must be used to ensure proper functionality of unit . Feed the Stop valve by fastening to the unit Inlet. Note: Ensure the supplied washers are in place before connecting inlet and the Stop Valve.
Feed the other point of Stop Valve to the incoming water supply. Ensure that the backplate of the unit is flat on the wall and positioned squarely. Tighten the fixing screws.
Turn on the water supply and check for leaks in the pipework connection to the shower.
NOTE:At this stage no water can flow through the unit.
ELECTRICAL CONNECTION
WARNING:THIS UNIT MUST BE EARTHED.
SWITCH OFF THE ELECTRICITY SUPPLY.
The cable entry points are shown in the figure below. Determine the cable entry to the unit.
Side entry - Poke the electrical cable through the Rubber grommet.
Route the cable into the shower unit and connect to the terminal block as follows:-
Live cable to terminal marked ' L ' Neutral cable to terminal marked ' N Earth cable to terminal marked '@'
IMPORTANT: Fully tighten the terminal block screws and ensure that no cable insulation is trapped under the screws. Loose connections can result in cabling overheating. DO NOT switch on the electricity supply until the cover has been fitted.
